> When we directly use buffer-flush options of the mysql sink
> (sink.buffer-flush.max-rows and sink.buffer-flush.interval) can not increase
> throughput.
> We must set 'rewriteBatchedStatements=true' into mysql jdbc url, for
> 'sink.buffer-flush' to take effect.
> Such as: 'jdbc:mysql://ip:3306/dbname?rewriteBatchedStatements=true'
> I want add a method appendUrlSuffix in MySQLDialect to auto set this jdbc
> option.
> Many users forget or don't know this option.
> Inspired by alibaba DataX.
